Re: print before take Scanner input not working
This was introduced sometime after Maven 3.3.9 (after Netbeans 11.1). Running
Netbeans 12.1 with Maven from Netbeans 11.1 is a work around.

Re: print before take Scanner input not working
The build tool is important here.
I think you are experiencing: NETBEANS-4617
The fix for that is in 12.2: https://github.com/apache/netbeans/pull/2270
It is marked to be backported to NetBeans 12.0-u2

Hello,
For many years, and both with NetBeans and with just a terminal, I
have used methods like this, to prompt the user to enter (say) an integer:
public static int inkeyInteger( String message ){
System.out.print( message );
Scanner console = new Scanner(System.in);
return console.nextInt();
}
Now in NetBeans 12, this code fails - the message is not printed until
after the user supplies data to the Scanner.
I have tried all the possible orderings of these 3 lines of code, and
passing the Scanner, etc. etc. I have searched StackOverflow.
It can be worked around if I print the message before calling a method
containing the scanner definition and next() call. This will require
changing hundreds of method calls throughout a large program.
Is there a workaround or patch etc.?

print before take Scanner input not working
Hello,
For many years, and both with NetBeans and with just a terminal, I have used
methods like this, to prompt the user to enter (say) an integer:
public static int inkeyInteger( String message ){
System.out.print( message );
Scanner console = new Scanner(System.in);
return console.nextInt();
}
Now in NetBeans 12, this code fails - the message is not printed until after
the user supplies data to the Scanner.
I have tried all the possible orderings of these 3 lines of code, and passing
the Scanner, etc. etc. I have searched StackOverflow.
It can be worked around if I print the message before calling a method
containing the scanner definition and next() call. This will require changing
hundreds of method calls throughout a large program.
Is there a workaround or patch etc.?
